[Tutor] Help with the technique "Menu Processing"

[Andrew Wilkins]

Hi Juno,

What you need to do is set up the class so...

1) Each method's first argument is self. self refers to the instance itself,
if you don't know.

eg.
> 	def send_priv_msg(connection, nick, text):
> 		... send code ..
should be:
def send_priv_msg(self,connection,nick,text):
	blah blah blah

2) The msgtype dictionary's values should have self before the variables, to
tell python to look in the instance's own namespace.

eg.
> 		self.msgtype = {"priv":send_priv_msg,
should be:
self.msgtype={"priv":self.send_priv_msg, #and so on...

Now when you call them, it should be fine and dandy!

def send_msg_by(connection, nick, text, type):
> 		self.msgtype[type](connection, nick, text)

*looks puzzled*
You had it right in that one! =)

Hope you can understand my badly written attempt at helping...

Andrew
